WILLIAM S-HARKEY, OF OROVILLE, CALIFORNIA.

BROADCAST GRAIN- sowlNG MACHINE.

SPECIFLCATION -forming part of Letters Patent No. 342.644, dated May 25, 1886. Application filed November-12. 1885. Serial No. 182,594. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM SHAEKEY, a citizen ofthe United States of America, residing at Oroville, in the county ofButte and State of California, have invented certain new and useful Improvements in Broadcast Grain-Sowing Machines; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable ot-hers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of broadcast seed-sowers which are adapted to be used in connection with a wagon, so as to distribnte the seed from the rear portion of said Wag` on; and myinvention consists more especially in the construction and combination of the parts, as will be hereinafter fully set forth and specically pointed out in the claims.

In the accompanying drawings, which illustrate my invention, Figure 1 is a side View of my improvement, showing the same attached in position for use upon awagon-body. Fig. 2 is a rear view. Fig. 3 is a perspective view of a seed-sowing apparatus, showing the same detached from the wagon. Fig. 4 is a plan view, and Fig. 5 is a detail view, of one of the distributors.

In the accompanying drawings, A represents the wagon-body, A the rear axle, and A the rear Wheel of the wagon, these parts being of ordinary construction and forming no part of my invention, a further description whereof is not necessary. The wheel A has removably attached thereto by means of bolts a crown-wheel, B, which consists of two rims, a a, which are connected to each other by pins a', which pins form the teeth with which the gear-wheel C, which is attached to the seed-sowing apparatus will engage. The gear-wheel Gis provided on its periphery with tapering and deepicut teeth b, and the thickness of said wheel C at its periphery is slight, lso that should the wheel B, which is attached to the supporting-wheel A, not run iu line, the rotation of the gear-Wheel C Will not be affected. By this construction the crown-wheel B may have a slight irregular vertical as well as lateral movement, and it will not effect the rotation ofthe gear-Wheel C.

c represents the loose hub upon which the gear-wheel C is mounted, said hub having its inner face formed so as to engage with a sliding clutch c', which is mounted on the shaft D.

E represents a suitable frame, which is prol vided with corner-posts, e, upper transverse beams, e', andlowertransverse beams,e, which are provided with bolt-holes, through which pass bolts for attaching the said frame to the bottom of the wagon-body.

frepresents intermediate cross-beams, which form bearings for the shafts, that will be hereinafter set forth.

The shaft D is journaled in bearings attached to the upper sides of the beamsf, and said shaft carries near the bearing farthest from the gear-wheel C a large cog-wheel, F, which is keyed securely to said shaft, and adjacent to the cog-wheel F within the frame is secured a flanged pulley, F.

G represents a shaft, which is journaled in bearings located rear of the shaft D, and said shaft is provided, on a line with the gear-wheel F, with a pinion, g, with which said gear-wheel meshes, and the outer endv of said shaft projects under the frame E for rigidly attaching thereto crown-wheel H H, the teeth of which engage with vertical pinions h, which arejournaled in horizontal bearings attached to the upper beams, e', of the frame, and the shaft It', which carries the pinions 71, extends upwardly into the hopper I, and is provided immediately under said hopper With distributing-plates J, as shown in Fig. 5.

To one side of the pinion g, so as to be about 011 a central line with the hopper, is attached a cam, t', over which passes the end of a connecting-bar, i', the upper end being pivotally attached to the projecting arm, which is secured upon a transverse rod which is j onrnaled in the hopper, so that when the shaft G is rotated the stirrers 7c will be oscillated, said stirrersI being located on the rod K adjacent to the feed-openings through which the seed passes from the hopper.

L represents a bent bar, which isjournaled in the rear of the beams e e of the frame E, so

IOOI

that its bent end, which isbifnrcated, willengage with a recess in the sliding clutch, and

its opposite end, l, is bent upwardly, so as to l xo having a tendency to throw said'clutch against the hub of the wheel C, and when it is desired to throw said clutch out of engagement with the hub of said wheel the lever L is moved so that the thickest portion of the wedge will be under the bent portion l. Thus it will be seen that by simply moving the lever the seed-distributing device can be thrown in and out of gear with the drive-wheel A. The hopperI is provided with acentral partition, m, which 2o covers the rock-bar of the rod k.

M represents the bottom plate of the hopper, which is secured rigidly to the upper transverse beam of the frame E` and said plate is provided with slotted openings m', above z5 which are located the circular feed-plates or disks N, which are pivotally attached to the upper ends of the shafts h', and these feedplates are cach provided with openings fn, which will register with the slotted openings 3o in the plate M, and by adjusting these feedplates the position of the supply of the grain upon the distributers can be regulated. These disks are provided on their cuter edges with serrations or notches o, with which the lbent ends of the spring-armsO will engage to hold them in position after they have been adjusted,

and by means of these, with plates, the throw or spread of the grain can be regulated, and when the grain is thrown too much behind the 4o wagon the holes are moved forward,thus causing the grain to be spread, and if the grain is being sown too thin by moving the holes backward a larger quantity will be fed upon the distributers and the grain will be sown thicker.

I? P represents cut-offs, which are connected to a rock-bar, P', which engages with atoothed segment attached to the frame, so that by moving the cut-offs rearwardly the holes in the feed-plates can be covered, and the size of 5o said openings can be increased or diminished by movingsad plates over said openings. Thus the cut-ofi' will regulate the movement of grain fed upon the rotary distributers, and the openings in the feed-plates will govern the spread of said grain.

R represents the frame of an endless conveyer, which is connected to and held in position by bars attached thereto, and to the frame E, and under the bottom of said conveyer-belt is placed the grain which it is de sired to sow. The belt which drives the endless conveyer passes over` the flanged pulley attached to the shaft D, and from thence between rollers r r, which are adjustable upon the frame and serve as a belt-guide, said belt passing over` the pulley R', which is attached to the upper shaft ofthe conveyer. The upper end of this conveyer will be located above the hopper, and the grain will be fed into the same therefrom.

The dstributers, as shown in Fig. 5, have vertical plates, j, which throw the grain outwardly, and bottom pieces, j', upon which the grain will strike after leaving the hopper.

By making the wheel B as hereinbefore described it forms an eficient means for conveying the motion from the wagon-wheel, and is more effective and less expensive than a cha-inbelt, beveled gearwheels, or other equivalent form of gearngs, and the twin distributers, being arranged in pairs, throw the grain from the center outwardly, one of Said distributers throwing the grain t-o the right, while the other throws the same to the left.

What I claim as new, and desire to secure by Letters Patent, is- 4 1. In a broadcast seed-distributing apparatus, a frame, E, adapted to be removably secured to a wagon body and provided with horizontal shafts D and G, the shaft I) having wheel C, which engages with a wheel, B, attached to the wagon-wheel, the cog-wheel F, mounted on said shaft, so as to engage with the pinion on the shaft G, crown-wheels H H, and pinionshh, for rotating the shafts on which the distributers J are secured, and a lever for throwing the wheel C out of engagement with the shaft D, and an endless elevating-belt with buckets for carrying the grain from the wagonbody to the hopper, the parts being combined and organized substantially as shown, and for the purpose set forth.

2. The feed-plates N, pivoted above the bottom of the hopper and provided with openings n and serrations o, lthe spring-catches O, for engaging with said serrations, substantially as shown, and for the purpose set forth.

In testimony whereof I afiix my signature in presence of -two witnesses.

WILLIAM SHARKEY.
